Summary

This clinical study aimed to compare the effectiveness of two minimally invasive approaches for masking molar-incisor hypomineralization (MIH) opacities and to evaluate esthetic perceptions of children and their parents. Participants with MIH-affected incisors received either resin infiltration or etch-bleach-seal treatment. Esthetic outcomes and satisfaction levels were assessed using standardized scales.

Detailed description

Molar-incisor hypomineralization (MIH) is a qualitative enamel defect that often leads to esthetic concerns, particularly in anterior teeth. Minimally invasive treatment approaches such as resin infiltration and etch-bleach-seal techniques have been proposed to improve the appearance of MIH opacities. This study aimed to compare the effectiveness of these two approaches in masking MIH opacities in permanent incisors and to evaluate esthetic perceptions from both children and their parents. Esthetic perceptions related to dental appearance were evaluated using the ''Child's and Parent's Questionnaire about Teeth Appearance''. The color masking effectiveness of resin infiltration and the etch-bleach-seal (EBS) technique on MIH-related anterior enamel opacities were evaluated using a spectrophotometer (VITA Easyshade® V, Sackingen, Germany). The findings are expected to contribute to evidence-based decision-making for minimally invasive esthetic management of MIH.

Conditions

• Molar Incisor Hypomineralisation
• Enamel Hypomineralization
• Tooth Discoloration

Interventions

Type	Name	Description
OTHER	Resin infiltration	A minimally invasive dental procedure used to mask enamel opacities associated with molar incisor hypomineralization. The technique involves etching the enamel surface, drying with ethanol, and applying a low-viscosity resin infiltrant (Icon®, DMG), followed by light curing and polishing in a single clinical session.
OTHER	Etch Bleach Seal Technique	A minimally invasive dental procedure used to improve the appearance of enamel opacities associated with molar incisor hypomineralization. The technique includes phosphoric acid etching, application of sodium hypochlorite for bleaching, and sealing with a resin-based sealant, followed by light curing and polishing in a single clinical session.
